What must bolt torque on tower connections match?

The correct answer emphasizes the importance of adhering to specific guidelines set forth in manufacturer or TIA-222 specifications for bolt torque on tower connections. TIA-222 is a widely recognized standard that provides detailed criteria for the design, manufacture, and installation of telecommunications towers, including requirements for connections. Ensuring that bolt torque matches these specifications guarantees structural integrity and safety, as it determines the tension and strength of the connection, helping to prevent failures due to excessive vibration or environmental factors.

Following manufacturer specifications is also critical, as manufacturers often test their products and determine optimal torque levels based on material properties and design. Adhering to these standards helps maintain consistency, reliability, and performance in tower installations. This is particularly crucial in the telecommunications industry, where equipment must endure various weather conditions and operational stresses.

In contrast, the other options lack the precision and authority that the correct answer provides. General practice guidelines may offer helpful insights but do not carry the same weight as established industry standards. Relying on previous torque levels is also risky, as they may not reflect current best practices or changes in design or materials. Thus, following manufacturer or TIA-222 specifications is essential to ensure safe and reliable tower operations.
